Idaho Claims Dispute & Statutory Guide
Idaho operates an At-Fault automobile insurance framework under Title 41 and Title 49 of the Idaho Code. The state follows modified comparative negligence with a 50% bar under Idaho Code § 6-801. Medical providers bill optional first-party Medical Payments (MedPay) and protect receivables by filing statutory medical and hospital liens with the county recorder under Idaho Code § 45-701.
Statutory Framework & Jurisdiction
At-Fault / Traditional Tort (Modified Comparative Fault & Idaho Medical Lien Act)
Idaho does not mandate Personal Injury Protection (PIP) insurance. Medical costs resulting from motor vehicle collisions are funded through optional first-party Medical Payments (MedPay) coverage, private health insurance, or third-party automobile liability insurance. Under Idaho Code § 6-801, an injured person may recover damages only if their negligence was less than the negligence of the person against whom recovery is sought. Healthcare providers and hospitals enforce statutory medical liens on third-party settlements under Idaho Code Chapter 45-7.
PIP / MedPay Coverage & Medical Fee Rules
optional Med Pay Coverage
MedPay is optional in Idaho (commonly written in limits of $1,000 to $10,000+ per person), providing no-fault reimbursement for reasonable medical, surgical, dental, hospital, and ambulance expenses resulting from an automobile accident
made Whole Doctrine
Under Idaho common law, an insurer's right of subrogation for MedPay benefits is subordinate to the Made-Whole doctrine, preventing recovery from a third-party settlement until the insured's total damages are satisfied
assignment Of Benefits
Healthcare providers routinely obtain patient assignments of MedPay benefits for direct claims submission to automobile insurers
